Dictionary<string, List<string>> and LINQ, C#

Question

I have a question. I would like to use LINQ to filter strings in Values (List<strings>) in my Dictionary<string, List<string>>. I want to remove string containing word "time".

How can I do in the simplest way?

EDIT:

Dictionary<string, List<string>> dict = new Dictionary<string, List<string>>
dict.Add
{("1stList", new List("time", "water", "pc")});
dict.Add("2ndList", new List("cat", "dog", "bird)});

Dictionary looks this way simplified.

I just want to delete "time" from 1st list.

Answer 1

Try

var myDict = new Dictionary<string, List<string>>
{
  {"1", new List<string>{"time", "clock"}},
  {"2", new List<string>{"clock"}}
};

myDict
  .Select(kvp => new KeyValuePair<string, List<string>>(
    kvp.Key, kvp.Value.Where(v => !v.Contains("time")).ToList()))
  .ToDictionary(kvp => kvp.Key, kvp => kvp.Value);
// {"1", {"clock"}, "2", {"clock"}}
